Question

5. Covalent molecules have low m.p. because:
a. Covalent bond is less exothermic
b. Covalent bond is weaker than ionic bond
c. Covalent molecules are held together by Vander Waal's forces
d. None of these​

Answer 1

Answer:

HOPE IT HELPS YOU!!

Explanation:

covalent bonds holding the molecules together are very strong, but these are largely irrelevant to the physical properties of the substance. Physical properties are governed by the intermolecular forces - forces attracting one molecule to its neighbours - van der Waals attractions or hydrogen bonds.
